Type `T` must be a complete type. In other words, inherits from __true_type only if expression `T(std::move(variable1))` won't throw (`variable1` is a variable of type `T`). __compat Without some (C++11 noexcept shall work correctly) help from the compiler, `is_nothrow_move_constructible` will never report that a class or struct has a non-throwing copy-constructor; this is always safe, if possibly sub-optimal. Currently (February 2013) MSVC-12.0, Clang and GCC 4.7 have the necessary compiler support to ensure that this trait "just works". __header ` #include ` or ` #include ` [endsect]
